mybatis报错:

void updateFndContainerItems(List<Long> list);
<update id="updateFndContainerItems">
    update  fnd_container_item set delete_flag = 1 where id in
    <foreach item="item" index="index" collection="list" open="(" separator="," close=")">
    #{item}
  </foreach>
</update>
报错信息:
Query is: update  fnd_container_item set delete_flag = 1 where id in
         (  
        ?
       , 
        ?

拿到打印的sql和参数,在Navicat中执行报错:

去掉空格后是ok的:

为什么呢?

最后改为参数的类型是Array,则在使用时,collection属性要必须指定为 array

updateFndContainerItemsByIds(Long[] ids);
    <update id="updateFndContainerItemsByIds">
        update  fnd_container_item set delete_flag = 1 where id in
        <foreach item="item" index="index" collection="array"
                 open="(" separator="," close=")">
            #{item}
        </foreach>
    </update>
